Coosje van Bruggen (b. 1942, Groningen, The Netherlands, d. 2009, Los Angeles) was a sculptor, art historian, and critic who collaborated extensively with her husband, the artist Claes Oldenburg. Throughout her career, van Bruggen held positions at various institutions including the Stedelijk Museum in Amsterdam; Sonsbeek 71, Artforum; and the Yale University School of Art. She also authored numerous art historical books. Van Bruggen’s first collaboration with Oldenburg was in 1976, when Trowel I, originally shown at Sonsbeek 71, was rebuilt and relocated to the sculpture garden of the Kröller-Müller Museum in the Netherlands. In 1978, van Bruggen moved to New York, where she continued to work with Oldenburg. Together, the pair executed more than forty large-scale projects, which have been sited in various urban surroundings in Europe, Asia, and the U.S.
